New point version.

Changes with Apache 2.4.60

  *) SECURITY: CVE-2024-39573: Apache HTTP Server: mod_rewrite proxy
     handler substitution (cve.mitre.org)
     Potential SSRF in mod_rewrite in Apache HTTP Server 2.4.59 and
     earlier allows an attacker to cause unsafe RewriteRules to
     unexpectedly setup URL's to be handled by mod_proxy.

  *) SECURITY: CVE-2024-38477: Apache HTTP Server: Crash resulting in
     Denial of Service in mod_proxy via a malicious request
     (cve.mitre.org)
     null pointer dereference in mod_proxy in Apache HTTP Server
     2.4.59 and earlier allows an attacker to crash the server via a
     malicious request.

  *) SECURITY: CVE-2024-38476: Apache HTTP Server may use
     exploitable/malicious backend application output to run local
     handlers via internal redirect (cve.mitre.org)
     Vulnerability in core of Apache HTTP Server 2.4.59 and earlier
     are vulnerably to information disclosure, SSRF or local script
     execution via backend applications whose response headers are
     malicious or exploitable.

     Note: Some legacy uses of the 'AddType' directive to connect a
     request to a handler must be ported to 'SetHandler' after this fix.

  *) SECURITY: CVE-2024-38475: Apache HTTP Server weakness in
     mod_rewrite when first segment of substitution matches
     filesystem path. (cve.mitre.org)
     Improper escaping of output in mod_rewrite in Apache HTTP Server
     2.4.59 and earlier allows an attacker to map URLs to filesystem
     locations that are permitted to be served by the server but are
     not intentionally/directly reachable by any URL, resulting in
     code execution or source code disclosure.
     Substitutions in server context that use a backreferences or
     variables as the first segment of the substitution are affected.
     Some unsafe RewiteRules will be broken by this change and the
     rewrite flag "UnsafePrefixStat" can be used to opt back in once
     ensuring the substitution is appropriately constrained.

  *) SECURITY: CVE-2024-38474: Apache HTTP Server weakness with
     encoded question marks in backreferences (cve.mitre.org)
     Substitution encoding issue in mod_rewrite in Apache HTTP Server
     2.4.59 and earlier allows attacker to execute scripts in
     directories permitted by the configuration but not directly
     reachable by any URL or source disclosure of scripts meant to
     only to be executed as CGI.

     Note: Some RewriteRules that capture and substitute unsafely will now
     fail unless rewrite flag "UnsafeAllow3F" is specified.

  *) SECURITY: CVE-2024-38473: Apache HTTP Server proxy encoding
     problem (cve.mitre.org)
     Encoding problem in mod_proxy in Apache HTTP Server 2.4.59 and
     earlier allows request URLs with incorrect encoding to be sent
     to backend services, potentially bypassing authentication via
     crafted requests.

  *) SECURITY: CVE-2024-38472: Apache HTTP Server on WIndows UNC SSRF
     (cve.mitre.org)
     SSRF in Apache HTTP Server on Windows allows to potentially leak
     NTML hashes to a malicious server via SSRF and malicious
     requests or content

     Note: Existing configurations that access UNC paths
     will have to configure new directive "UNCList" to allow access
     during request processing.

  *) SECURITY: CVE-2024-36387: Apache HTTP Server: DoS by Null
     pointer in websocket over HTTP/2 (cve.mitre.org)
     Serving WebSocket protocol upgrades over a HTTP/2 connection
     could result in a Null Pointer dereference, leading to a crash
     of the server process, degrading performance.

  *) mod_proxy: Fix DNS requests and connections closed before the
     configured addressTTL.  BZ 69126.  [Yann Ylavic]

  *) core: On Linux, log the real thread ID in error logs.  [Joe Orton]

  *) core: Support zone/scope in IPv6 link-local addresses in Listen and
     VirtualHost directives (requires APR 1.7.x or later).  PR 59396
     [Joe Orton]

  *) mod_ssl: Reject client-initiated renegotiation with a TLS alert
     (rather than connection closure).  [Joe Orton, Yann Ylavic]

  *) Updated mime.types.  [Mohamed Akram <mohd.akram outlook.com>,
     Adam Silverstein <adamsilverstein earthboundhosting.com>]

  *) mod_ssl: Fix a regression that causes the default DH parameters for a key
     no longer set and thus effectively disabling DH ciphers when no explicit
     DH parameters are set. PR 68863 [Ruediger Pluem]

  *) mod_cgid: Optional support for file descriptor passing, fixing
     error log handling (configure --enable-cgid-fdpassing) on Unix
     platforms. PR 54221.  [Joe Orton]

  *) mod_cgid/mod_cgi: Distinguish script stderr output clearly in
     error logs.  PR 61980.  [Hank Ibell <hwibell gmail.com>]

  *) mod_tls: update version of rustls-ffi to v0.13.0.
     [Daniel McCarney (@cpu}]

  *) mod_md:
     - Using OCSP stapling information to trigger certificate renewals. Proposed
       by @frasertweedale.
     - Added directive `MDCheckInterval` to control how often the server checks
       for detected revocations. Added proposals for configurations in the
       README.md chapter "Revocations".
     - OCSP stapling: accept OCSP responses without a `nextUpdate` entry which is
       allowed in RFC 6960. Treat those as having an update interval of 12 hours.
       Added by @frasertweedale.
     - Adapt OpenSSL usage to changes in their API. By Yann Ylavic.

[Tim Tassonis]

Looks like an sa case, that one...

[Tim Tassonis]

Careful when updating apache, they more or less silenty threw out AddType and replaced it with AddHandler, resultung in php configs not working anymore....

[Tim Tassonis]

They just released 2.4.61, due to the php thingy

[Tim Tassonis]

Fixed in commit 60314d0869, issued sa-12.1-067

[Douglas R. Reno]

The PHP bug was also assigned a CVE, so the SA needs to be updated for that:

Severity: important

Affected versions:

- Apache HTTP Server 2.4.60

Description:

A regression in the core of Apache HTTP Server 2.4.60 ignores some use of the legacy 
content-type based configuration of handlers.   "AddType" and similar configuration, 
under some circumstances where files are requested indirectly, result in source code 
disclosure of local content. For example, PHP scripts may be served instead of 
interpreted.

Users are recommended to upgrade to version 2.4.61, which fixes this issue.

Timeline:

2024-07-01: reported

What I'll do for that is just note the additional CVE number and update the text a bit.

[Tim Tassonis]

Well, I don't think that's neccessary, as the php bug was fixed in 2.0.61, and we never had 2.0.60 in the first place.
